The AirTAC AirTAC SDA80X30SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 30mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA80X30SB is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted assembly merges the barrel, rear cover, piston, and rod to drastically reduce mounting depth compared to conventional round-body units. At 80 mm bore, it generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, operating at speeds between 30-500 mm/s.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, plus a male M22x1.5 threaded piston rod (-B) for secure load coupling. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage.

Drives heavy ejector pins in plastic injection molding machines where the short riveted body saves valuable axial space inside the tooling platens.
Positions thick gauge steel sheets under mechanical stamping presses, utilizing the 2513.3 N push force to secure parts before the impact cycle.
Raises loaded pallets in packaging lines, where the male M22x1.5 rod end firmly attaches to lifting forks and the fixed NBR bumper softens the final descent.
When sizing this 80 mm bore model, consider stepping down to the SDA63, which yields 1558.6 N of push force at 0.5 MPa, or scaling up to the SDA100, which provides 3927 N at the same pressure. The SDA80X30SB offers a calculated safe working load of roughly 1508 N (about 60% of its 0.5 MPa rating) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 30 mm stroke, PT3/8 port, male M22x1.5 rod thread, and the integrated sensor magnet. Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end without locking the load; utilize an external rod lock or pilot-operated check valve if position holding is critical.
Quick checklist
This 80 mm bore double-acting cylinder provides 2513.3 N push and 2267.8 N pull at 0.5 MPa, 3518.6 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum push of 513 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No, the SDA80X30SB uses a fixed NBR bumper at each end to decelerate the piston near stroke completion, which is not an adjustable air cushion. For high-speed or high-energy applications, you should add an external shock absorber or reduce the approach speed to prevent premature wear.
